tially rotatable within the other to open and close the carrier and one of said members being insertible endwise within the other and to the outer end of each member a head of felt is secured. In use these carriers are subjected to considerable hardship and in' carriers heretofore in general use there has been difficulty due to the means for securing the members together coming loose. To avoid that difficulty two screws insertible through the ends of the members and the adjacent felt have been used with a single nut on the inside for both screws. But even this has been found to be insufficient as the bolts or screws still are liable singly to unscrew and escape.

The immediate object of this invention is to prevent these screws from getting loose and to accomplish this object by simple means that will not mar the end of the carrier or in any manner interfere with its use.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims.

In the drawings Figure 1 is a plan view of the carrier, of the kind to which this invention relates. Fig. 2 is a central vertical section of one end thereof. Fig. 3 is an end elevation of one end of the carrier with the central felt removed. Fig. t is a plan view of the disk for holding the screws in place. Fig. 5 is a central section through the end of the carrier on the line 55 of Fig. 2.

The carrier consists chiefly of the felt heads 10, the outer casing or member 11 and the inner casing or member 12. These casings or members 11 and 12 are substantially similar, being tubular, closed at one end and open at the other and each provided with an opening at 13. The inner member fits rather snugly within the outer member but loosely enough to turn therein so that when the openings in the two members register the carrier will be open for the insertion or removal of cash, and the carrier closes by turning the two members relative to each other so that the outer member will close the opening of the inner member.

There is nothing peculiar in the foregoing parts so far as this invention is concerned, nor in the means for securing the members together. The fastening means herein shown consists of the disk 15 and a cap-like member 16 secured to and within the closed end of the outer member 11. The cap-like member 16 fits within the open end of the inner member 12 of the carrier so that said inner member will turn upon said part 16. To that end the part 16 consists of a disk with a flange extending at a right angle from the periphery thereof. This flange has a groove 17 extending partially about its external periphery and the stop 18 secured to the inner member lies in said groove and thereby the two members 11 and 12 are held together and prevented from separating longitudinally. l urtherniorc, the stop 18 as the members 11 and 12 are relatively rotated, stops or limits such rotary movement by engaging one or the other of the ends of the groove 17.

A pair of screws 20 extend through the felt 10 the closed end of the outer member 11, the disk 15, and the end of the member 16 and screw into a single duplex nut 21 on the inside of the carrier, for holding those parts together. The outer ends of the screws 20 have heads on them and the screws pass through the washer disk 23 that is embedded or countersunk in the centrally located circular recess 24. Upon the 'asher 23 a screw-holding or looking disk 25 is superimposed and is provided with an oppositcly located recess 26 in which the heads of the screws 20 he and the heads of these screws are flattened at 27 on each side so that the screws cannot be turned when the disk 25 is in place, as shown in Fig. 3. The screw-holding disk 25 is held in place by a felt plug 28 that is wedged tightly into the circular recess 24 in the felt head 10. This construction will prevent the screws 20 from coming loose and escaping as they are held at both ends by single means so that they cannot turn either simultaneously or independently of each other and however long the carrier may be used the parts cannot be separated.

It will be readily understood that a number of equivalents for maintaining the screw holding disk 25 in its locking position may be provided that would occur to any ordinary mechanic skilled in the art and which may be substituted without departing from my invention; that modification such as would result from a reversal of parts and would occur to an ordinary mechanic skilled in the art may also be substituted without departing from my invention.

What I claim as my invention and desire to secure by Letters Patent is:

l. A cash carrier including shells, a felt head on one end of the shells and centrally recessed, bolts extending through the felt head and one end of one of the shells, means within the shells into which said bolts screw, a removable locking plate in the recess in the felt head that engages the outer ends of the bolts that prevents the same from rotation, and removable means for holding said plate in locking position.

2. A cash carrier including shells, a felt head having a central recess in the end thereof, a pair of screw bolts for uniting the felt head to a shell, the heads of said bolts being in said recess and flattened on their sides, a plate fitting in said recess in the felt head provided with recesses into which the heads of the screw bolts extend and fit and which are so narrow that said plate prevents the screw bolts from turning, and a plug insertible in the recess in the felt head for holding said locking plate in place.

3. A cash carrier including shells, a felt head with a central recess in the end there of, a pair of screw bolts for uniting the felt head to a shell, the heads of said bolts lying in said recess in the felt head and being flattened on their sides, a single duplex nut into other shell, means within the closed end.

of the outer shell and the open end of the inner shell for holding said shells together, i

a felt head against the closed end of the outer shell with a central recess in the end thereof, a pair of screw bolts extending through said felt head, the closed end of the outer shell and the means for securing the two shells together, the heads of said bolts lying within the recess in the felt head and being flattened on their sides,.a single duplex nut within said shells into which said bolts screw, a locking plate within said recess having recesses therein fitting about the heads of said bolts so as to prevent the turning thereof, and a plug insertible in the recess in the felt head, substantially as set forth.

In witness whereof, I have hereunto affixed my signature in the presence of the witnesses herein named.
